SPECTFICATTON forming part of Letters Patent No. 431,259, dated July 1,1890..

Application filed March 26, 1890. Serial No. 345,312- (No model.)

To all whom it may concern:

Be it known that I, SAMUEL EMRICH, of Reno, in the county of WVashoe andState of Nevada, have invented a new and Improved Railway-Spike, ofwhich the following is a specification, reference being had to theannexed drawings, forming a part thereof, in which- Figure 1 is a sideelevation, partly in section, of my improved spike, showing the spikedriven into place and the fastening devices ready for operation. Fig. 2is a horizontal section taken -on line x 00 in Fig. 1. Fig. 3 is avertical section showing the lateral fastening-plates being forcedoutwardly, and Fig. 4.- is a vertical section showing the manner ofdisplacing the lateral fastening-plates previous to withdrawing thespike.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to provide a railway-spike with means forholding it in place in the wood into which it is driven.

My invention consists in a spike provided with a longitudinal cavity andlateral mortises communicating with the cavity, plates fitted to themortises, and a bar fitted to the cavity and provided with awedge-shaped end for forcing the plates outwardly in the mortises andcausing them to project into the wood at the sides of the spike.

The invention also consists in the combination, with the spike andlateral plates, of an auxiliary plate and a wedge for forcing thefastening-plates out of their mortises.

The spike A, which is of the usual form, is provided with a longitudinalcavity a, extending from the head 1) toward the point e. In

the body of the spike are formed mortises cl 7 d, which communicate withthe cavity a. In the mortises (Z d are placed plates e e, which arewider than the thickness of the walls of the spike. To the cavity a isfitted a bar B, having a wedge-shaped end f.

The spike is driven into the wood with the plates c e in the mortises,as shown in Fig. 1. The spike is secured against accidental loosening byforcing the plates 6 e outward by driving the bar B into the cavity a,as shown in Fig. 3. The outer edges of the plates project into the wood,as shown, and prevent the spike from being withdrawn.

When it is desired to remove the spike, a'

plate 9, provided with the projection h, is inserted in the cavity a ofthe spike, with the projection h extending into one of the mortises d.The wedge O is inserted between the plate g and the wall of thelongitudinal cavity a and driven in so as to force the plate c outwardbeyond the outer wall of the spike. The plate 6' is forced outward inthe same Way, as shown in Fig. 4, when the spike may be withdrawn fromthe wood.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with a spike A, pro vided with thelongitudinal cavity a and mortises (Z cl, of the plates e e,substantially as specified.

2. The combination, with a spike A, pro vided with the longitudinalcavity a and 1nortises (Z d, of the plates 6 e and the bar B,substantially as specified.

3. The combination, with the spike constructed substantially asspecified and provided with plates 6 c, of the plate 9 and the wedge O,substantially as specified.
